You also ask about why an vaccination won't work if you're already infected: It won't work because the virus has already gotten a foothold and is already established in your body. The vaccine causes your body to produce a certain amount of hep B antibodies, which basically gives you a security system that detects and attacks the virus when it first enters your body...when it is at its weakest and is much more easily eradicated. Without the vaccine antibodies, the virus can replicate and get a foothold before the immune system mounts a decent offense to its presence.
And I'm almost certain once you test + for HBV antibodies you cannot donate blood anymore (HCV antibody + definitely). Hope you're feeling better soon and test negative on your hep B test.
